So far here, we are in the dry slot and the pressure is 999 millibars and steadily falling. SPC is really concerned about possible tornadoes throughout the area. Looking at the visible sat imagery, it looks like the LLC/MLC (whatever it is...:lol:) is going to pass almost directly over top of me or pretty darn close. (I'm in between New Bern and Morehead City, that is extending the current motion out). Also of note, the power did go out for a second or two last night, made me mad because I was kicked off the internet and had to wait for it to reboot. :lol:

I suppose many have their own "magic number", mine is 997 millibars( or about 29.44 inches as I prefer to state it). A storm of that magnitude is no laughing matter. (If anyone has any doubts, check you're local weather for today's barometer reading). Occasionally, along the gulf coast, you can have pressure readings of 1004 millibars or so associated with strong low pressure systems and the passage of frontal boundaries(although this is infrequent). I've found that the 997 MB reading signifies a more important status when referring to landfalling tropical systems along the gulf coast. The atmosphere seems to become much more unstable at that point, with chances of tornadic development greatly increased. So when I hear of pressure readings of 995 MB's along the Atlantic Coast with the passage of Barry (or whatever you want to call him now, lol, this is so silly) I am impressed. I know that you are experiencing a significant storm.


it looks worse i think than it really is.... if the pressure is 993mb or so, the pressure here in southeast va is 997mb... no pressure gradient to speak of... so the wind is not that bad... maybe gust to 15mph... all up and down the coast winds look to be 10mph or so...

Good point, Charley, the gradient. I failed to take that into account. Thanks.
